  On the other hand, as a simple screening for mild depression in Japan, for example, a check of SRQ-D Toho University is used in local governments and hospitals as a simple questionnaire (see, for example, Patent Document 2) ). This is, for example, Question 1: Is your body so tired? Question 2: Are you worried about noise? The suspicion of depression is simply diagnosed by selecting from four types of answers of “No”, “Occasionally”, “Frequently”, and “Always” for 18 questions such as.

  As described above, it is known that simple diagnosis is performed by a simple linguistic questionnaire, and the symptoms are alleviated by online dialogue using a computer.

  On the other hand, Japanese Patent Application Laid-Open No. 2003-108674 (Patent Document 1) discloses a system that performs counseling using a personal computer. Japanese Patent Laid-Open No. 2013-109656 (Patent Document 2) determines that the user is stressed by inputting text to a computer that the user normally uses even if the user does not consciously undergo an examination. An apparatus is disclosed.

  On the other hand, apart from stress and fatigue reduction, for example, there are home appliances that communicate by voice. For example, a robot cleaner (RX-V200) sold by Sharp Corporation has a function of performing speech recognition, speech synthesis, and conversation with a user (Non-Patent Document 3).

  Hereinafter, embodiments of the present invention will be described with reference to the drawings. In the following description, the same parts are denoted by the same reference numerals. Their names and functions are also the same. Therefore, detailed description thereof will not be repeated.

[Technology]
With reference to FIG. 1, the technical idea which concerns on this Embodiment is demonstrated. FIG. 1 is a diagram showing a configuration of an interactive home appliance system 20 according to the present embodiment. The home appliance system 20 includes an utterance unit 21, a voice input unit 22, a storage unit 24, a drive mechanism 25, and a communication unit 26. The control unit 27 includes a determination unit 23. The control unit home appliance system 20 can interact with one or more users 10, 11, 12, and the like.

  In the following description, the home appliance system 20 may be realized by a device that performs daily support. In one aspect, the device may include a privately usable household electrical machine appliance referred to as a so-called “home appliance” and a business-use office device. Home appliances include, for example, vacuum cleaners, refrigerators, air conditioners (hereinafter also referred to as “air conditioners”), televisions, lighting, blood pressure monitors, rice cookers, electromagnetic cookers, washstands, scales, home planetariums, and other appliances. May be included.

  In addition, the device in this embodiment is not limited to being used indoors, and may include devices used outdoors such as automobiles, bicycles, motorcycles, and electric chairs. Office equipment may include appliances that can be used by businesses such as copiers, facsimile machines, shredders, teleconferencing systems, video conferencing.

  For example, in a certain situation, the home appliance system 20 outputs a voice via the utterance unit 21 (first utterance). The user 11 answers in response to the voice. The voice input unit 22 receives an input of an answer by the user 11.

  The voice input unit 22 converts the answer into a voice signal. The communication unit 26 is connected to the Internet 30 and can communicate with the information communication terminal 40. The mode of communication is not particularly limited. The control unit 27 controls the operation of the home appliance system 20. In the control unit 27, the determination unit 23 determines the psychological state of the user 11 based on the signal and the data stored in the storage unit 24. This determination is made based on data stored in advance in the storage unit 24, for example. In another aspect, the determination unit 23 may connect to the Internet 30 via the communication unit 26 to communicate with the information communication terminal 40, and the information communication terminal 40 may make the determination.

  The determination unit 23 transmits a signal based on the determination result to the utterance unit 21. The utterance unit 21 outputs voice based on the signal (second utterance). When the user 11 listens to the voice (second utterance) output by the home appliance system 20, the psychological state may settle according to the content.

  In an aspect, the home appliance system 20 may be realized as one or more home appliances. In another aspect, home appliance system 20 may be realized by a home appliance and a server that can communicate with the home appliance.

  The identification of the users 10, 11, and 12 is performed using, for example, an operation of a dedicated switch assigned to each user, a face image, a fingerprint, a voiceprint, or other biological information. Note that the accuracy of identification need not be 100%, and may be such that, for example, in a family of four, the user is known. On the other hand, in another aspect, an authentication technique that requires 100% accuracy may be used. For example, 100% authentication technology may be used in hospitals or other medical facilities with a large number of inpatients, or in welfare facilities with a large number of residents. Alternatively, in still another aspect, the accuracy of identification may be variable.

  Examples of data used to determine a user's mental state include, for example, the content of conversation with a home appliance (voice recognition result), voice (speech frequency analysis result), a photographed user's face image, and a user's sweat rate. User body temperature, user breathing, etc. can be used. For conversation, the mental state can be estimated from the content of the answer. For a face image, for example, if the user's face turns red, the user can be estimated to be in an excited state. With respect to the amount of sweating, when the amount exceeds a predetermined amount, it can be estimated that the user is in an excited state. With respect to breathing, if a user's breathing is faster than the normal number of breaths, it can be estimated that the user is in an excited state.

  Alternatively, as yet another embodiment, the mental state of the user may be estimated based on the tone level of the user's voice. For example, if the voice tone is lower than normal, the user may be estimated to be more tired than normal. Conversely, if the voice tone is higher than normal, the user may be presumed to be excited.

[Usage mode of home appliance system]
With reference to FIG. 2, the technical idea which concerns on this Embodiment is further demonstrated. FIG. 2 is a diagram illustrating an aspect in which interactive home appliance system 20 is used. In one aspect, home appliance system 20 is realized as cleaning robots 211 and 221 that are one mode of home appliances.

  In the person's home 210, the cleaning robot 211 is connected to the refrigerator 213, the lighting 214, the television 215, and the air conditioner 216 via the router 212 so that they can communicate with each other. The refrigerator 213, the lighting 214, the television 215, and the air conditioner 216 each have a network function, and execute a specific operation based on a signal sent from the cleaning robot 211. The specific operation may include, for example, a process of displaying the contents of the refrigerator 213, a process of adjusting the brightness of the lighting 214, a process of adjusting the channel or volume of the television 215, and adjusting the temperature of the air conditioner 216.

  The house 210 is connected to the Internet 30. Other people's house 220, medical institution server 230, municipality server 240, business server 250, smartphones 260 and 270, and automobile 280 are connected to the Internet 30 so that they can communicate with each other.

  The other person's house 220 is a relative's house of a resident of the house 210, for example. A cleaning robot 221 exists in the house 220. The cleaning robot 221 is connected to the refrigerator 223, the illumination 224, the television 225, and the air conditioner 226 via the router 222 so as to be able to communicate with each other. The refrigerator 223, the illumination 224, the television 225, and the air conditioner 226 have the same functions as the refrigerator 213, the illumination 214, the television 215, and the air conditioner 216, respectively. Therefore, detailed description thereof will not be repeated.

  The medical institution server 230 is used by, for example, a hospital or other medical institution where the person or relative visits. The local government server 240 is used by the local government where the person or relative lives. The company server 250 is operated and used by an information provider for transmitting information to the cleaning robots 211 and 221, respectively. Each of the medical institution server 230, the local government server 240, and the business server 250 is realized by a computer device having a known configuration, for example.

  The smartphones 260 and 270 are used as information processing communication terminals by the members of the person who is providing the medical service to the person's family or the person. The information processing communication terminal is not limited to a smartphone, and a tablet terminal, a PDA (Personal Digital Assistant), or other terminal may be used by a family member or a member of a business operator. The configuration of the smartphones 260 and 270 can be easily understood by those skilled in the art. Therefore, description of the configuration will not be repeated.

  The automobile 280 has a network communication function and can be controlled by the cleaning robots 211 and 221 and other devices having a communication function.

(Example scenario)
Hereinafter, scenarios that can be assumed in the present embodiment will be described. In each of the following scenarios, the cleaning robot 211 is used as an example of home appliances, but the application target of the technical idea according to the present embodiment is not limited to the cleaning robot 211. The technical idea can be applied to, for example, a refrigerator 213, an illumination 214, a television 215, an air conditioner 216, an automobile 280, and other devices that have at least a voice recognition function and an information processing function.

(Scenario 1) <First embodiment>
As 1st Embodiment, the household appliances which have a dialogue function can perform the utterance which cares about the said user based on the conversation from a user. For example, the user returns home to the house 210. The user utters "I'm right". When the cleaning robot 211 recognizes the utterance, the cleaning robot 211 detects that the user is a user who has already been registered in the cleaning robot 211 based on previously registered voice information. The cleaning robot 211 issues an answer “Return” that is stored as information prepared in advance. Thereafter, when the user issues “clean up”, the cleaning robot 211 answers “OK” and starts executing the cleaning function. The cleaning robot 211 travels in accordance with a predetermined program and cleans the living loop and other rooms.

  When a predetermined condition is satisfied, the cleaning robot 211 asks, "Is you tired recently?" Here, the predetermined condition is, for example, that a predetermined time has elapsed since the user's last utterance, that the user who has interacted with the cleaning robot 211 is a registered user, etc. Can be included. In another aspect, the question utterance may be randomly performed based on a random number generated in the cleaning robot 211.

  In response to the question, the user replies to the cleaning robot 211 “Yes, because I am busy with work”. When the cleaning robot 211 recognizes the answer, the cleaning robot 211 performs a diagnosis of the user inside the cleaning robot 211 and acquires a diagnosis result. Alternatively, in another aspect, the cleaning robot 211 transmits an audio signal of the answer to the operator server 250 connected to the Internet 30. The business server 250 makes a diagnosis based on the audio signal and returns the diagnosis result to the cleaning robot 211.

  When the cleaning robot 211 obtains the diagnosis result, the cleaning robot 211 utters “If you can't do it”. In response to the utterance, the user replies “Yes, thank you”. When the cleaning robot 211 recognizes the answer, it answers “you are welcome”.

  If the user recognizes that the user is concerned about the cleaning robot 211 through such an interaction, the user's stress and fatigue may be alleviated.

(Scenario 2) <Second Embodiment>
As the second embodiment, the cleaning robot 211 can make an utterance that cares about the user with reference to the dialog history with the user.

  The cleaning robot 211 recognizes that the user is living a busy life with reference to the conversation history with the user who has recognized the voice. The dialogue history may include, for example, the time zone when the utterance was performed, the content of the utterance, and the like. The cleaning robot 211 speaks, "Do you get tired recently?" The user recognizes the utterance and replies “Yes, because I am busy with work”. When the cleaning robot 211 recognizes the answer, the cleaning robot 211 diagnoses the user. As described above, this diagnosis can be performed in the cleaning robot 211 or in an external server device (for example, the operator server 250) that can receive an audio signal from the cleaning robot 211.

  When the user detects that the user is more tired than the previous two weeks in the last two weeks, the cleaning robot 211 utters “Would you like to rest for a few days or travel?”. In response to the utterance, the user answers “Yes, thank you”. When the user is recommended to travel by the cleaning robot 211, the fatigue and stress of the user can be alleviated.

(Scenario 3) <Third embodiment>
As a third embodiment, the dialogue between the cleaning robot 211 and the user can be used for cooperation with a medical institution. In one embodiment, as in the case of scenario 2, the cleaning robot 211 utters “Have you tired recently?”. The user recognizes the utterance and replies “Yes, because I am busy with work”. When the cleaning robot 211 recognizes the answer, the cleaning robot 211 utters "If you can't do it". The user answers “Yes, thank you” to the utterance.

  When the cleaning robot 211 recognizes the answer, the conversation information about the fatigue of the user for the last two weeks is transmitted to the medical institution server 230. The medical institution server 230 is a hospital or other medical care / treatment facility in or near the local government where the user's home 210 exists. Instead of the mode in which the cleaning robot 211 transmits the dialog information to the medical institution server 230, the business server 250 that accumulates the dialog information in response to the request from the cleaning robot 211 sends the user's dialog information to the medical institution. You may transmit to the server 230. Further, the dialogue information transmission request may be transmitted not by the cleaning robot 211 but by the medical institution server 230 that has received the permission from the cleaning robot 211.

  The medical institution server 230 diagnoses the user based on the dialogue information. When the medical institution server 230 determines that the user needs a diagnosis by a doctor, the medical institution server 230 transmits such a determination result to the cleaning robot 211. The determination result is created by the medical institution server 230, for example, by adding the name of the attending doctor of the user, the day of the examination, or the like to one or more predefined templates. The cleaning robot 211 speaks based on such a determination result, “Professor Yamada of Psychosomatic Medicine says that he should come to the clinic once.” The user responds with “Yes” to the utterance.

  When the cleaning robot 211 recognizes the response, the cleaning robot 211 refers to the data stored in advance as the day of the medical examination of the attending physician and utters "Reservation at 6 o'clock next week?" In response to the utterance, the user answers “Please”. In response to the answer, the cleaning robot 211 communicates with the medical institution server 230 and applies for a reservation at 6 pm next Wednesday (for example, February 12) as medical treatment by the attending physician. When the reservation is accepted by the medical institution server 230, the cleaning robot 211 speaks to the user, “Wednesday, February 12, 6:00 pm”. When the user recognizes the utterance, the user answers “Thank you”.

  In this way, in one embodiment, the cleaning robot 211 arranges a reservation with a medical institution on behalf of the user as required by the user. In addition to the relaxation of feelings due to the dialogue as described above, the user can feel grateful that the cleaning robot 211 has booked an examination for the user. In another aspect, there may be a case where a reservation cannot be obtained at the date and time proposed by the cleaning robot 211. In this case, the cleaning robot 211 may inquire the medical institution server 230 about candidate date and time that can be reserved, and notify the user of the result of the inquiry as an alternative.

(Scenario 4) <Fourth embodiment>
As a fourth embodiment, an automobile 280 having an interactive function may interact with a driver who is a user instead of the home appliance. As one aspect, a case will be described in which an air conditioner control device has an interactive function and a diagnostic function.

  When the control device detects that the air conditioner is switched on, it uses a microphone (not shown) built in the automobile 280 and says, “Today, there is a lot of pollen, so the air cleaner is also moved together.” Speak. That there is much pollen can be acquired from the weather information which the control apparatus of the motor vehicle 280 receives via the internet 30, for example. In response to the utterance, the driver answers “Thank you”. When the air conditioner recognizes the answer, it refers to the driver attribute stored in the built-in memory of the control device and utters "Did you have hay fever today?" In response to the utterance, the driver replied, "It was terrible today." When the air conditioner recognizes the meaning of the answer, it utters "Please take care." When the driver recognizes the utterance, the driver answers “Thank you”.

  In this way, the driver's stress and fatigue can be alleviated by talking to the driver from the air conditioner. In addition, the operation of the air cleaner according to the content of the conversation can also contribute to alleviating stress and fatigue. The recognition of the driver's answer is not limited to the mode recognized by the air conditioner. For example, the vehicle 280 may be connected to the Internet 30 and the business server 250 or other external information processing apparatus may recognize the answer. The automobile 280 and the smartphone 260 owned by the driver may form a communication session by WiFi (Wireless Fidelity), Bluetooth (registered trademark) or other communication means, and the smartphone 260 may recognize the conversation of the driver.

  As another aspect, an output of a sensor mounted on the automobile 280 may be used. For example, it can be estimated that the mental state of the user is elevated from the vehicle speed obtained by the vehicle speed sensor. Alternatively, it may be estimated that the user's mental state is not normal when the accelerator depressing speed exceeds a normal speed, or when sudden braking or a sudden steering operation is performed. In such a case, the automobile 280 may perform an utterance that calms the user's spirit. Alternatively, in another aspect, the automobile 280 may perform music playback or fragrance delivery for that purpose.

(Scenario 5) <Fifth embodiment>
As a fifth embodiment, the automobile 280 may operate so as to prompt the user to operate based on a conversation with the user.

  As an example, when the controller of the automobile 280 detects that the seat belt of the driver's seat is worn, it says, “It seems that hay fever was severe today.” When the driver recognizes the utterance, it answers “Yes.” When the controller acquires the semantic content of the answer by internal voice recognition and analysis processing or from recognition processing by an external information processing device connected to the Internet 30, it will be “through a speaker (not shown)”. Please keep the window closed. I will activate the air purifier. " When the driver recognizes the utterance, the driver answers “Thank you”. Alternatively, the speaker may say “Close the window and activate the air purifier.” The controller may automatically close the window and activate the air purifier.

  In this manner, the automobile 280 starts speaking to the driver, so that the driver can feel the care of the automobile 280, so that the driver's fatigue and stress can be reduced.

(Scenario 6) <Sixth embodiment>
As a sixth embodiment, each home appliance provided in the house 210 may communicate with a home appliance in another house 220 or another smartphone 270 via the Internet 30. Hereinafter, a case where the resident of the house 210 (grandmother) and the resident of the house 220 (mother) are a family will be described.

  In a certain situation, a grandmother living in the house 210 performs a switch operation or utterance on the cleaning robot 211. The cleaning robot 211 starts cleaning while self-propelled in response to such an operation of the grandmother.

  The cleaning robot 211 pauses during cleaning in order to reduce the operation sound, and speaks "Thank you for always using it." In response to the utterance, the grandmother answers, “Thank you for this.” The cleaning robot 211 identifies that the speaker is a grandmother, and refers to the history of dialogue with the grandmother in response to the recognition result of the meaning content of the answer. From the history, the cleaning robot 211 detects that the word “tired” is frequently used in the grandfather's utterances so far. Therefore, the cleaning robot 211 utters, “Grandpa. I often say that I am tired at this time.” When the grandfather recognizes the utterance, he answers, "Yes, I'm tired of nothing." The cleaning robot 211 acquires the recognition result of the meaning content of the answer, and extracts the keyword “tired” from the answer. In one aspect, such keywords can be stored by the cleaning robot 211 and other home appliance systems themselves. In another aspect, the keyword can be registered with an operator or a local government that provides a so-called “watching service”.

  In response to the detection of the keyword “fatigue”, the cleaning robot 211 refers to a database held in the built-in memory and calculates the frequency of use of the keyword “fatigue”. The cleaning robot 211 detects that the number of uses of the word “tired” exceeds a certain number (for example, 30 times) within a predetermined period (for example, two weeks). The cleaning robot 211 communicates with the central control unit of the interactive home appliance system of the house 220 in response to such a detection result. In one aspect, the central control unit can be realized in a home server device provided in the house 220 or by a control device for a cleaning robot 221 or other household appliances. In another aspect, the central control unit may be provided in the local government server 240.

  For example, when the cleaning robot 221 receives the detection result as the central control unit, it starts communication with the smartphone 260 of “mother” who is one of the residents of the house 220. The cleaning robot 221 transmits a message to the smartphone 260. When the smartphone 260 receives the message via the Internet 30, instead of the cleaning robot 211, “It is a grandmother's vacuum cleaner, but grandmother has been“ tired ”30 times in the past two weeks. "I'm saying," and "Oh my grandfather, I feel like I'm at home now, so let's talk to my grandfather?" When the mother recognizes the utterance and replies “Please”, the smartphone 260 makes a call to the cleaning robot 211 configured to be able to make an Internet call using, for example, VoIP (Voice over Internet Protocol). . When the grandmother answers the call, the mother can interact with the grandmother.

  In this way, since the operation of the cleaning robot 211 is used as a trigger, a dialogue between the user (grandmother) of the cleaning robot 211 and a family (mother) living in a remote place is performed, so the loneliness and fatigue of the grandmother are alleviated. Can be done.

<Seventh embodiment>
In another aspect, as a seventh embodiment, a local government server 240 used by a local government that provides a so-called watching service may function as a central control unit. In this case, the cleaning robot 211 transmits a message including the keyword “tired” and the identifier of the speaker (grandmother living in the house 210) to the local government server 240.

  When the processor of the municipal server 240 receives the message, it accesses the resident database and adds the content of the message to the record of the grandmother who lives in the house 210. The processor counts the number of times “tired” or other keywords are received, and the number of times the word “tired” is used exceeds a certain number (for example, 30 times) within a predetermined period (for example, two weeks). Is detected. In response to the detection result, the processor transmits an utterance message to the mother's smartphone 260 registered in the local government server 240 as an applicant for the watching service. When the smartphone 260 receives the message, as described above, “It is a grandmother's vacuum cleaner, but grandmother has said that he has been“ tired ”30 times in the last two weeks.” And, “Oh my grandfather, I feel like I ’m at home now, so let ’s talk to my grandfather?” Even in this way, the grandmother's loneliness, fatigue, etc. can be alleviated.

  Note that, as described above, recognition of voice uttered by the user, extraction of meaning content, and other information processing can be performed inside an individual household electrical appliance such as the cleaning robot 211. Alternatively, in another aspect, the information processing may be performed in a medical institution server 230, a local government server 240, a business server 250, or other external server devices.

[Configuration of home appliance system]

  In the storage unit 809, the utterance content database 820 holds in advance content for the cleaning robots 211 and 221 to utter. In another aspect, the utterance content database 820 may hold unique utterance content according to the user of the cleaning robots 211 and 221.

  Referring again to FIG. 8, the cleaning robot 211 can be connected to the Internet 30. A provider server 250 is connected to the Internet 30. Therefore, the cleaning robot 211 can communicate with the provider server 250 on the cloud side. The business server 250 is realized by a computer having a known configuration as shown in FIG. 7, for example. The company server 250 includes a communication unit 251, a control unit 252, and a storage unit 256.

  The communication unit 251 includes the communication interface 7. The communication unit 251 communicates with the cleaning robot 211. The communication mode and protocol are not particularly limited.

  The control unit 252 includes a voice input reception unit 253, a voice recognition unit 254, and a response process execution instruction unit 255. The control unit 252 includes the CPU 1. When the CPU 1 executes the command, the CPU 1 can function as the voice input reception unit 253, the voice recognition unit 254, or the response process execution instruction unit 255. In another aspect, any of the voice input reception unit 253, the voice recognition unit 254, and the response processing execution instruction unit 255 may be configured as a dedicated processing circuit or other circuit.

  The voice input receiving unit 253 receives a voice signal that has been accepted by the cleaning robot 211 via the communication unit 251. The voice recognition unit 254 recognizes the content of the voice signal sent from the cleaning robot 211. The response process execution instructing unit 255 generates a process for responding to the cleaning robot 211 based on the recognition result of the signal sent from the cleaning robot 211, and sends the processing signal to the cleaning robot 211 via the communication unit 251. Send. When receiving the processing signal, the cleaning robot 211 utters a sound corresponding to the processing signal.

  The storage unit 256 is realized by the hard disk 5, for example. The storage unit 256 includes an utterance content database 258 and a state storage unit 259. The utterance content database 258 holds in advance contents for uttering through the speaker 804 of the cleaning robots 211 and 221. The state storage unit 259 holds the state of the cleaning robots 211 and 221 and the state of each user of the cleaning robots 211 and 221.

[Server control structure]
(Server side basic flow)
A control structure of server 310 according to one aspect will be described with reference to FIGS. FIG. 9 is a flowchart showing an example of a speech recognition process executed by the server 310 in order to understand the meaning of an utterance and select a message for dialogue. The server 310 has a configuration such as a computer 700, for example. FIG. 10 is a diagram illustrating an aspect of a database structure in server 310.

  In step S <b> 910, CPU 1 of computer 700 receives the voice transmitted from home appliance 350 through communication interface 7.

  In step S920, CPU 1 recognizes the voice received from home appliance 350 as voice recognition unit 316, and acquires a character string (also referred to as “input phrase”) indicating the recognized content. The mode of speech recognition processing is not limited. Further, CPU 1 identifies a speaker (user) to home appliance 350 based on user information registered in server 310.

  In step S930, CPU 1 analyzes the character string (input phrase) and interprets the intention of the user of home appliance 350.

  In step S940, CPU 1 obtains the current operation mode for each user of home appliance 350 (for example, all residents in house 210 who have been registered as users who receive services provided by server 310) from RAM 4 or hard disk 5. .

  In step S950, CPU 1 selects an operation mode. The operation mode to be selected can include a normal dialogue mode and a diagnostic mode. In one aspect, the CPU 1 selects an operation mode based on whether or not a condition for shifting to the diagnosis mode is satisfied. For example, it is determined whether or not it is necessary to shift to the diagnosis mode with reference to the history of interaction with the user specified in step S920. For example, the CPU 1 may determine the necessity of transition to the diagnosis mode, the time that has elapsed since the time when the previous diagnosis mode was executed, the keyword detected in the previous dialogue, and may be related to the diagnosis. It is determined whether or not the keyword is detected in the current utterance. When the normal dialogue mode is selected, the CPU 1 switches the control to step S960, and when the diagnosis mode is selected, the CPU 1 switches the control to step S1100.

  In step S960, CPU 1 determines the response content. In the normal dialogue mode, the server 310 generates a response based on the input phrase and performs voice utterance. First, the CPU 1 determines the content of the response. The response is not limited to voice, and may include movement of home appliance 350, blinking of a light (not shown) of home appliance 350, and the like in another aspect.

  More specifically, referring to FIG. 10, CPU 1 refers to response content table 1000 and input phrase table 1010 stored in hard disk 5. The response content table 1000 includes an input phrase ID for specifying an input phrase and a specific input phrase 1002. The input phrase table 1010 includes a response ID 1011 for identifying a response by the home appliance 350, an input phrase ID 1012 indicating an input phrase related to the response, an utterance message 1013 indicating the specific utterance content by the home appliance 350, And an operation pattern 1014 for identifying the operation of the device 350. The operation patterns A to C may include, for example, normal operation, rotation operation, and other operations.

  CPU1 selects the utterance message 1013 corresponding to an input phrase. For example, when a plurality of utterance messages exist as selection candidates for the same input phrase, the CPU 1 randomly selects one utterance message from among the plurality of utterance messages. For example, when the user makes a greeting “good morning” to the home appliance 350, the CPU 1 randomly selects one utterance message from the three response IDs = 1 to 3 as a response to the greeting. .

Referring to FIG. 9 again, in step S962, CPU 1 determines whether or not to start the diagnostic mode. As conditions for starting the diagnosis mode, for example, the following cases are conceivable.
-The content of the first conversation of the day between the user and the home appliance 350-When the evaluation of the input phrase (see FIG. 12) is negative. As a result, the user is talking normally with the home appliance 350 every day. Thus, the server 310 can naturally start diagnosis of the stress or fatigue state of the user. If CPU 1 determines to start the diagnostic mode, CPU 1 can start a diagnostic mode process (step S1100), which will be described later.

  In step S980, CPU 1 synthesizes voice using the character string of the determined utterance message, and generates voice data for causing home appliance 350 to utter.

  In step S990, CPU 1 transmits response information including operation data 1014 corresponding to the voice data and the selected utterance message to home appliance 350. When home appliance 350 receives the response information, home appliance 350 speaks based on the audio data and performs an operation according to operation pattern 1014. Thereby, the dialogue between the user and the home appliance 350 is realized, and the stress and fatigue of the user can be reduced according to the utterance content of the home appliance 350.

  When CPU 1 determines to select the diagnosis mode, in step S1100, CPU 1 executes a diagnosis mode process to be described later.

Thereafter, the process returns to step S910.
[Server control structure and data structure]
(Diagnosis mode start processing flow)
With reference to FIG. 11 and FIG. 12, the control structure of server 310 in one aspect will be further described. FIG. 11 is a flowchart showing an example of processing executed by server 310 in the diagnosis mode. As an embodiment, when the server 310 starts the diagnosis mode, unlike the normal dialogue, the home appliance 350 starts an inquiry to the user, so this processing is the main processing (FIG. 9). Are executed independently. In the main process, when the CPU 1 determines that the diagnosis mode is started, the main process can be executed asynchronously.

  FIG. 12 is a diagram conceptually showing one mode of storage of data for diagnosis in hard disk 5. The hard disk 5 stores a diagnosis message table 1210 and a diagnosis history table 1220. The diagnostic message table 1210 includes a diagnostic ID 1211 for identifying the contents of the diagnosis, a diagnostic message 1212 having a character string representing an inquiry to the user, and a validity period 1213 of the diagnostic message. For example, once the diagnosis message “Is appetite?” With diagnosis ID = 4 is selected, the diagnosis message cannot be selected until 7 days have passed. The diagnosis history table 1220 includes a user ID 1221 for identifying a user of the home appliance 350, an input date and time 1222 when the utterance from the user is received, a diagnosis ID 1223 for identifying the used diagnosis message, and the diagnosis message An utterance message 1224 indicating the content, an input phrase 1225 indicating a character string of the utterance from the user, and an evaluation 1226 of the utterance are included.

  Referring to FIG. 11 again, in step S1110, CPU 1 waits for a determination result (flow from step S950 to step S1100 in FIG. 9) that the diagnostic mode is started.

  In step S1120, CPU 1 obtains the time elapsed since the last utterance using time information from an internal clock (not shown) and data of input date 1222.

  If the elapsed time is equal to or longer than a certain time (for example, 1 minute) in step S1130, CPU 1 determines that the utterance from the user of home appliance 350 has disappeared (YES in step S1130), and asks the CPU concerned user. To start.

  In step S1130, CPU 1 determines whether or not a predetermined time has passed. For example, when the time elapsed since the last utterance is equal to or longer than a predetermined time (for example, 1 minute) set in advance, the CPU 1 determines that the utterance from the user of the home appliance 350 has been lost. If CPU 1 determines that a certain time has elapsed since the time from the last utterance was acquired (YES in step S1130), CPU 1 switches control to step S1140. If not (NO in step S1130), CPU 1 returns control to step S1120. For example, when the normal conversation between the home appliance 350 and the user continues, the elapsed time should be within a certain time, and as a result, the CPU 1 waits for the next process until the conversation ends. It will be.

  In step S1140, CPU 1 determines the contents of diagnosis. For example, the CPU 1 randomly selects a diagnostic message 1212 from the diagnostic message table 1210 (FIG. 12). Since it is meaningless to repeat the same inquiry using the same diagnostic message, the CPU 1 also refers to the diagnosis history table 1220 and excludes the diagnostic message (that is, the utterance message 1224) used for the most recent inquiry. A diagnostic message 1212 may be selected from the remaining candidates.

  In step S1150, CPU 1 synthesizes voice using the character string of the selected diagnostic message and generates voice data for causing home appliance 350 to utter, as in the main process.

  In step S1160, CPU 1 transmits response information including audio data to home appliance 350.

  In step S1170, CPU 1 records the diagnostic content including the selected diagnostic message and user ID in diagnostic history table 1220, and updates diagnostic history table 1220. As for the input phrase 1225 and the evaluation 1226, the CPU 1 stores data after receiving a response from the user. Therefore, it is desirable that the input phrase 1225 and the evaluation 1226 be blank (NULL) at this time.

  In step S1180, CPU 1 updates the operation mode. More specifically, the CPU 1 sets the operation mode of the server 310 for the user to “diagnosis mode”. Therefore, after that, when the server 310 receives the voice of the user of the home appliance 350, the CPU 1 can execute the diagnosis mode process.

Thereafter, control is returned to step S1110.
Note that the server 310 may have a configuration in which the totals within a certain period or the history of a specific user is aggregated using the history shown in FIG. With such a configuration, the server 310 can transmit a report to a user of the home appliance 350, a medical institution, a local government, or the like as necessary.

(Diagnosis mode processing flow)
With reference to FIGS. 13-15, the control structure of the household appliance system 20 is further demonstrated. FIG. 13 is a flowchart illustrating an example of the diagnosis mode process executed by CPU 1. In the diagnosis mode, the server 310 makes several questions to the user via the home appliance 350, and diagnoses the user's stress, fatigue, and other mental conditions based on the response from the user to the question.

  14 and 15 are diagrams conceptually showing one mode of data storage in hard disk 5, respectively. In one embodiment, as shown in FIG. 14, the hard disk 5 holds an answer evaluation table 1400. The answer evaluation table 1400 includes an answer ID 1401 for identifying an answer from the user, a diagnosis ID 1402 for identifying a diagnostic message 1212 used for the inquiry, an input phrase 1403 indicating a character string obtained from the answer, and a diagnosis result. Evaluation 1404 shown. The diagnosis ID 1402 corresponds to the diagnosis ID 1211.

  As shown in FIG. 15, the hard disk 5 includes a normal message table 1510 and a healing message table 1520. The normal message table 1510 includes a message ID 1501 and a message 1502. The healing message table 1520 includes a message ID 1521 and a message 1522.

  The healing message table 1520 may store a message 1522 that makes the healing feel more than the message 1502 included in the normal message table 1510. The message 1522 that makes the user feel healing includes, for example, a phrase that cares for the user, a phrase that prompts an action for improving physical condition or reducing stress, a phrase that brings laughter to the user, a phrase that impresses the user, and the like. Phrases that care about the user are, for example, “I'm doing my best”, “Don't do my best”, “I'm worried”, etc., but can also include other phrases. Phrases that encourage behavior to improve physical condition or reduce stress are, for example, “If you sleep early,” “If you have a rest tomorrow,” “Tomorrow there is a community baseball tournament,” etc. Phrases can also be included. The phrase that brings laughter to the user may include, for example, puns such as “futon is futon”, jokes, and the like.

  In another aspect, audio content 1530 for reducing stress may be stored in the server 310 in place of a message that causes healing. The audio content 1530 can include data for outputting voices of animals such as dogs, cats, birds, poetry readings, music, and the like.

  In yet another aspect, by changing the voice quality between the voice output based on the message 1502 included in the normal message table 1510 and the voice output based on the message 1522 included in the healing message table 1520 There may be a difference in the degree of healing. One aspect of the change in voice quality is, for example, that a normal message is output with a male voice and a healing message is output with a female voice. Further, when both the normal message and the healing message are uttered by a female voice, the healing may be further felt by changing the voice color of each message.

  In another aspect, the degree of healing may be differentiated by changing the pitch (high and low) of the output voice. As one aspect of the change of the pitch of the voice, for example, when you want to be energetic as a healing, the pitch of the voice may be higher than the standard, and conversely, to include the gentleness of the voice as a healing The voice pitch may be lower than the standard.

  In another aspect, the degree of healing may be differentiated by changing the utterance speed of the output voice. For example, when it is desired to increase the degree of healing, the user may feel kindness by making the utterance speed slower than the standard speed. Conversely, the user may be encouraged by making the utterance speed faster than the standard.

  In another aspect, the degree of healing may be differentiated by changing the volume of the output audio. For example, when it is desired to increase the degree of healing, the user may feel kindness by making the sound smaller than the standard. Conversely, the user may be encouraged by making the sound louder than the standard.

  In another aspect, the degree of healing may be differentiated by changing the intonation of the output voice. For example, when you want to increase the healing degree, "Hello" that every phrase, is output as it is, for example, Kansai valve to change the intonation, may be in phrases like feel the friendliness and laughter to the user. In still another aspect, the above-described embodiments for making a difference in the degree of healing may be appropriately selected and combined.

  Moreover, in another Example, the healing message table according to each user may be comprised. Such a healing message table may include, for example, a table for outputting a female voice to a male user, a table for outputting a child's voice to an elderly person such as grandpa or grandma, and the like. In yet another aspect, when the server 310 is configured to be able to obtain the latest information from other information communication devices, the server 310 can provide a yesterday's soccer game result to a user who is interested in soccer. Also, the player's play information and the like may be obtained from the other information communication device, and voice data for speaking, for example, “Yes, yesterday's XX player's goal was amazing” may be synthesized. Since speech synthesis can be realized by a known technique, detailed description will not be repeated. In addition, a healing message table may be configured according to the target user of home appliance 350.

  Referring to FIG. 13 again, in step S1310, CPU 1 refers to diagnosis history table 1220, and acquires the content of the utterance uttered from home appliance 350 immediately before (diagnosis ID 1223).

  In step S1320, CPU 1 refers to answer evaluation table 1400 and evaluates input phrase 1403 obtained from the utterance. As an example, the CPU 1 checks whether or not there is an input phrase 1403 that matches the input phrase 1225 from the user among the diagnosis IDs that match the diagnosis ID 1223 of the diagnosis message 1224 uttered from the home appliance 350 immediately before. The answer evaluation table 1400 is searched. For example, a so-called editing distance is used as the degree of coincidence. If there is an input phrase 1403 that matches the input phrase 1225, the CPU 1 sets the value of the evaluation 1404 associated with the input phrase 1403 as the evaluation for the input phrase 1403. On the other hand, if there is no matching input phrase 1403, the CPU 1 sets the evaluation of the answer to “0”.

  For example, when the immediately previous question (utterance message 1224) is “How is today?” (Value “1” of the diagnosis ID 1211) and the user's response to the question is “good”, the response ID 1401 Since = 1, the evaluation for this input phrase is “+1”. On the other hand, even if the user's answer is an affirmative answer “Yes”, the evaluation may vary depending on the contents of the question (see, for example, the case of answer ID 1401 = 7, 11). Therefore, if the user's answer “Yes” is an answer (answer ID 1401 = 7) to the question “Do you sleep well last night?” (Diagnosis message 1212 corresponding to diagnosis ID 1211 = 2) of home appliance 350, the value of evaluation 1404 Becomes “+1”. On the other hand, if the answer “Yes” is an answer (answer ID = 11) to the question “Do you feel that you have recently fallen asleep?” (Diagnosis message 1212 corresponding to diagnosis ID 1211 = 3) of home appliance 350, evaluation 1404 The value of is “−1”.

  In step S1330, CPU 1 records the evaluated input phrase and the evaluation result in diagnostic history table 1220 as input phrase 1225 and evaluation 1226.

  In step S1340, CPU 1 determines whether or not to continue the diagnostic mode. This determination is made based on, for example, a signal given to server 310, a result of answer to home appliance 350, or the like. As a specific example, the CPU 1 counts the number of questions in the current diagnostic mode, and ends the diagnostic mode when a predetermined number of questions are made. If the number of times is too large, questions will be frequently asked, which will be a burden on the user. Therefore, for example, the number of times is preferably about three times, but the number of times is not limited to three and may be one. When CPU 1 determines to continue the diagnosis mode (YES in step S 1340), control is switched to step S 1350. If not (NO in step S1340), CPU 1 switches control to step S1370.

(When continuing diagnosis mode)
In step S1350, CPU 1 determines the diagnostic content for home appliance 350 to ask the user next.

  In step S1360, CPU 1 records the diagnosis content in diagnosis history table 1220.

(When exiting diagnostic mode)
In step S1370, CPU 1 evaluates the mental state of the user of home appliance 350 based on the diagnosis result. More specifically, for example, in the current diagnosis mode, when the value of the evaluation 1226 recorded in the diagnosis history table 1220 is negative, the CPU 1 is in a poor mental state, that is, the user has some stress or Judge that you are tired. When the home appliance 350 makes multiple inquiries, the CPU 1 determines the mental state of the user using the total value of the evaluations 1226 of the answers to the respective inquiries.

  In step S1380, CPU 1 determines the content of response by home appliance 350 according to the evaluation result. For example, the CPU 1 refers to the normal message table 1510 and the healing message table 1520 to determine the response content. When the CPU 1 determines that the user's mental state is bad, the CPU 1 randomly selects a message 1522 for response from the healing message table 1520. When such a message 1522 is uttered by the home appliance 350, an effect of improving the mental state of the user can be expected. On the other hand, when the CPU 1 determines that the mental state of the user is not bad, the message 1502 for response is randomly selected from the normal message table 1510.

  In step S1390, CPU 1 changes the operation mode of server 310 from the diagnostic mode to the normal mode.

(Diagnosis based on history)
The diagnosis of the user's mental state is not limited to the evaluation in the current diagnosis mode. For example, the diagnosis may be performed based on the past history of the user, and a more effective diagnosis can be performed. .
For example, the following diagnostic methods can be considered.
・ Diagnosis using all the diagnosis results on the day (total evaluation value for one day)
・ Diagnosis using all diagnosis results within a predetermined period (total value of evaluation values for the last three days) ・ Evaluation value is calculated every day, and the number of days on which the evaluation value is negative is determined in advance Diagnosis that judges that the user's mental condition is bad (for example, for 3 days) ・ Evaluation value is calculated every day, and the average value of evaluation values every week is also calculated. If the evaluation value for the most recent one week is negative and the difference between the evaluation value for the most recent one week and the evaluation value for the immediately preceding one week is equal to or greater than a predefined threshold, Judgment, it is determined that the mental state is bad.

  In the above description, for example, as shown in FIGS. 10, 12, and 15, voice data corresponding to each message is stored in advance in a storage device such as the hard disk 5 as data for speech. Embodiments are illustrated. However, the manner of holding data for audio output is not limited to the above example. For example, a character string and data for speech synthesis may be held in a storage device, and a healing message may be uttered as speech by performing speech synthesis using a character string corresponding to the content of the utterance. . The mode of speech synthesis is not particularly limited, and waveform connection type speech synthesis and other known methods can be used.

  The healing message is not limited to a conversation that ends in a single conversation, but may be an utterance that continues the conversation. For example, when the home appliance system 20 recognizes the answer of the speaker, the home appliance system 20 may utter an utterance including a question prompting the next answer as a healing message. More specifically, in general, there are various means for reducing a person's fatigue and stress, and the degree of reduction varies depending on the person. Therefore, the home appliance system 20 may sequentially issue messages that prompt actions that can contribute to reducing fatigue and stress. As an example, the home appliance system 20 responds to the speaker's response such as “Would you like to rest a little?”, “Well, what about taking a walk?”, “How about a trip?”, “How about eating a delicious cake?” Thus, utterances that draw out the next answer may be sequentially performed.

  In many cases, the healing message 1522 is prepared in the server 310 in advance. In another aspect, message 1522 may be one that can be registered in server 310 or home appliance 350 from another information communication terminal. For example, referring to FIG. 2, when a family member of a house 210 is staying at a remote house 220, a family member of the house 210 can use a business server 250 or other server 310 via a smartphone or other information communication terminal. Alternatively, the message may be blown into the cleaning robot 221 or other equipment provided in the house 220. A visitor in the house 220 can reduce fatigue and stress by listening to the voice of the family from the cleaning robot 221 and others.

<Eighth Embodiment>
[When video is used]
In each of the above embodiments, the case where voice is used as an inquiry to the user by the home appliance 350 has been exemplified. The question to the user is not limited to voice, but may be, for example, text or other images or video.

  Accordingly, another application example of the technical idea will be described with reference to FIG. FIG. 16 is a diagram illustrating an aspect in which television 215 which is household electrical appliance 350 according to the eighth embodiment interacts with the user.

  For example, in a certain situation A, the television 215 is not turned on but is in a standby state. Thereafter, when the server 310 determines that the diagnosis mode is to be started, or when a predetermined timing arrives, the television 215 displays an image or message that asks the user's state. Furthermore, the television 215 may display a message that prompts an operation of a remote controller (not shown).

  When the user responds to the display on the television 215 by operating the remote controller, the response result is transmitted to the server 310 and the state of the user is diagnosed. When the server 310 determines that the user's mental state is not good, the server 310 transmits a command for displaying video, image, or text information that invites the user to laugh to the television 215. The television 215 displays such video, image, or character information in response to receiving the command. When the user visually recognizes such a display, the user may laugh unintentionally, so stress and fatigue can be reduced.

  As described above, according to the technical idea according to the present embodiment, the home appliance 350 constituting the home appliance system 20 asks the user by voice or video, obtains the user's answer to the inquiry, and obtains the user's answer. Diagnose mental status. Since the home appliance system 20 outputs audio and video based on the diagnosis result to the user, the stress and fatigue of the user who has recognized the audio and video can be alleviated.

  As is clear from the above description, in this embodiment, the definition of housework (= activity in daily life) is not limited to cleaning, washing, and cooking. Therefore, the home appliances in this embodiment are not limited to household electronic machines in a narrow sense such as cleaning robots, washing machines, rice cookers, air conditioners, and televisions. Home appliances may include, for example, a car equipped with a navigation system that supports driving by linguistic communication with respect to movement, an electric wheelchair that assists those who have difficulty walking, a power suit that supports hard work, and the like. In other words, the technical idea according to the present embodiment may be any device that can execute a function that assists daily life by means of speech, characters, images, and other linguistic interfaces.

<Ninth embodiment>
In the above-described example, the case where voice or video is used to reduce fatigue or stress is shown, but the reduction of fatigue or stress is not reduced only by voice or video. For example, it can be realized by release of a fragrance (ie, odor), projection of an image (ie, color), dance (ie, movement) of home appliances, and the like. More specifically, in another aspect, home appliance 350 releases a pre-filled fragrance when it receives a user's answer to the utterance and determines that the user feels stress or fatigue. In another aspect, home appliance 350 may have a projector function. In this case, when the home appliance 350 receives the user's answer to the utterance and determines that the user feels stress or fatigue, the home appliance 350 is directed toward the ceiling of the installed room or on the side. To display the video. The video can include, for example, a video with a high healing effect, a video of a foreign landscape, and the like.

  In yet another aspect, cleaning robot 221 as home appliance 350 may move while singing when it is determined that the user feels stress or fatigue in response to the user's answer to the utterance. Voice and movement can reduce user stress and fatigue.

  In summary, the technical idea according to the present embodiment is realized by the following configuration, for example.
